Before "Smallville" goes on a spring hiatus, it will introduce Super Boy who is none other than the combination of Clark Kent and Lex Luthor. Lucas Gabreel guest stars as Alexander Luthor who is now known as Conner Kent aka Kon-El aka Superboy. He possesses all the powers of Superman but he also has a dark side like Lex.

The synopsis for the episode called "Scion" reads: Lionel and Tess go head to head in a battle for the Luthor name. Clark and Lois are stunned by Tess' latest present to them. Superboy may wreck a havoc in the episode but it looks like he won't do too many damage. After all, the producers said previously that "there [will] be no doubt about how Lex becomes the great rival in Clark Kent's life. He is the villain of the story."

Meanwhile on "Supernatural", Sam, Dean and Bobby set out in search of The Mother of All's latest monster. While investigating, they run into Samuel and Gwen, who are also hunting the creature. Samuel and Bobby get into a heated fight about how to handle the case.

For "Supernatural" cliffhanger means killing some people. Jensen Ackles, Jared Padalecki, and Jim Beaver had shot a somber funeral scene for this episode. Beaver tweeted that he doesn't remember the last time he was so excited about a script.

"Scion" and "And Then There Were None" air March 4.
